Figure 2. (A) Schematic diagram of MSTP-PE-HMPA-CNT composite cathode in situ fabricated by polymerization of the PE precursor. SEM images of CNTs (B) before and (C) after coating the slurry. (D) MSTP-PE-HMPA/15 for different cycles collected with a capacity of 1000 mAh g-1 at a current density of 200 mA g-1[31]. Reproduced from Ref.[31] with permission from American Chemical Society. (E) Three-phase interfacial reaction confined by the dissolved oxygen in a conventional LOB. (F) SWNT/[C2C1im] [NTf2] CNG. SWNTs (gold) were untangled by a π-cation/π-electron interaction with the imidazolium cation of [C2C1im]+ (green), thereby forming physical gels with cross-linked networks. The [NTf2]- ions (purple) were anchored in the gel through electric neutrality. Oxygen fills the entire CNG and electrons conduct along the CNTs. Lithium ions transfer from the ionic liquid electrolyte outside into the CNG[32]. Reproduced from Ref.[32] with permission from John Wiley and Sons. MSTP: Modified silyl-terminated polyether; PE: polymer electrolyte; HMPA: hexamethylphosphoramide; CNTs: carbon nanotubes; MSTP-PE-HMPA/15: the MSTP-PE-HMPA with 15 wt.% HMPA; LOB: lithium-oxygen battery; SWNTs: single-walled carbon nanotubes; IL: ionic liquid; CNG: cross-linked network gel.
